The magnicon, a scanning beam microwave amplifier tube related to the gyrocon is of interest as a possible replacement for klystron amplifiers in future linear accelerators. The authors report an experimental study of the gain between two half-wavelength, 5.7 GHz TM[sub 110] pillbox cavities, separated by a quarter-wavelength drift space, and powered by a 170A, 500 keV electron beam immersed in an 8.1 kG magnetic field. These cavities constitute the first section of a planned multicavity deflection system, whose purpose is to spin up an electron beam to high transverse momentum ([alpha] [triple bond] v[sub [perpendicular]]/v[sub z] [approx gt] 1) for injection into the output cavity of a frequency-doubling magnicon amplifier. They have observed a gain of [approximately]15 dB in the preferred circular polarization, at a frequency shift of approximately [minus]0.18%, in the opposite circular polarization, at a frequency shift of approximately +0.06%. These results are in good agreement with theory.
